| Abstract: | The Connecticut River Watershed Atlas is a web mapping application that serves to share natural resource and environmental databases in a watershed setting tied to stream network and catchment features of the National Hydrography Dataset Plus (NHDPlus). To meet the project objective, a Service-Oriented Architecture (SOA) toolset has been developed for the Connecticut River Watershed Atlas. The benefits of the custom toolsets allow organizations to perform geospatial analysis by delineating watersheds on-the-fly via the NHDPlus navigation functionality performed on the server side of the application. This is accomplished through a geoprocessing model executed by ArcGIS Server. The NHDPlus Watershed and Feature Report tools allow users to access multiple precomputed stream and watershed characteristics for approximately 12,500 stream segments. The SOA will include a web application and ArcGIS Explorer clients. ArcGIS Server 9.3 beta technology will be used as the foundation for geospatial feature extraction. Custom query tools built using ArcGIS Server allow users to explore the data and locate features. Linkages to stream-gaging information in near real-time from the USGS National Water Information System has also been incorporated into the Atlas. Future possibilities will be discussed including incorporation of higher-resolution StreamStats web services. This presentation will include demonstrations of the web application, ArcGIS Explorer, and other clients under development. Connecticut River Watershed Atlas project and technical Q&A session will follow presentation. |
